Expertise & Solution


Secondary treatment is the biological degradation of soluble organic compounds in wastewater. Typically, we recommend suspended growth aerobic biological system for industrial applications. This system effectively reduces BOD, COD and other soluble organics substances in wastewater. High strength organics effluent requires the use of anaerobic process followed by aerobic process if necessary. The various secondary treatment we design and build are :

  • Sequential Batch Reactor (SBR)
  • Conventional Activated Sludge (CAS)
  • Extended Aeration Activated Sludge (EAAS)
  • Upflow Anaerobic Sludge Blanket (UASB)
